Daily Intelligence Brief: Softbank AI model and SK hynix NAND flash developments - August 25, 2025
Softbank developed a Transformer-based Artificial Intelligence (AI) model focused on wireless signal processing. The model improved uplink throughput by approximately 20% compared to traditional methods. In a demonstration using GPUs in a live Over-the-Air (OTA) wireless environment, the system achieved gains in throughput and ultra-low latency, confirming effective real-time operation.
The new architecture's uplink channel interpolation enhanced throughput by about 8% over traditional Convolutional Neural Network (CNN) methods. Comparatively, a 30% increase was noted against baseline models without AI support, bolstering communication quality in real-world settings. The model processed data with an average time of 338 microseconds, well below the 1 millisecond threshold for real-time 5G communications.
Softbank plans to commercialize these validated technologies to advance communication quality and network efficiency through AI-RAN strategies, potentially optimizing Capital Expenditure (CAPEX) and enhancing value via ongoing software updates as AI models evolve.
SK hynix Inc. announced the mass production of its 321-layer 2Tb QLC NAND flash, marking a milestone in the QLC technology landscape. This product is designed to double current capacities, improving the architecture by increasing the number of operational units within each chip, which enhances performance through better parallelism.
The 2Tb NAND flash reportedly delivers data transfer speeds double those of its predecessors, with significant enhancements to write and read performance. This product is aimed at sectors requiring low power consumption, such as AI data centers, and it underscores SK hynix’s strategic alignment with market demands for high-capacity storage solutions.
Research on Open RAN (ORAN) (O-RAN) indicates stabilization with cumulative revenues nearing $10 billion. The findings highlight the importance of the Open Fronthaul interface within telecom networks. However, despite a positive long-term outlook, the report notes a decline in supplier diversity, with a concentration of providers increasing in several regions.
Market traction for Open Radio Access Network (O-RAN) has been uneven, experiencing a 40% revenue decline over two years due to reduced 5G investment. Recent data shows signs of recovery with year-over-year revenue growth, suggesting a potential stabilization in the near future. Despite existing challenges, the forecast for long-term growth remains constructive.
Brightspeed has completed its fiber network deployment across 11 Kansas communities, reaching roughly 23,000 families and businesses. This deployment addresses gaps in connectivity, especially in areas previously underserved by fiber-optic services.
The affected areas now benefit from improved high-speed internet access, supporting activities like remote work and online learning. Brightspeed targets expanding its service to over 57,000 families and small businesses, promoting engagement with local communities regarding these advancements.
